The 35-year old Canadian international has returned to TFC after leaving the Reds in 2011 when he was traded to New York Red Bulls.
The owner of TFC, Maple Leafs Sports & Entertainment boss Tim Leiweke, told The Canadian Press on Tuesday that the move has worked out well for all parties from a financial point of view.
"Tim B (general manager Tim Bezbatchenko) and I got on the phone with Dwayne a couple of weeks ago and had a good hour conversation about what it is he wants to do, what happened here (in his first stint) and where we're trying to go," Leiweke said in relation to the 2011 trade of De Rosario.
"And we aired it all out."
He added of the cut-price deal: "I think (Bezbatchenko) and Dwayne and Dwayne's agent did a very good job of trying to find a fair deal.
"And to Dwayne's credit, he understands that if this is about winning, we had to have enough room left within our (salary) cap to add a couple more pieces here."
